TO ALL WHOM -IT'MAY CONOERN:

Be it known that we, JOHN PoLnnMUs, of Jersey City, Stat'eof NewlJersey, and CHRISTIAN H. LILIENTIIAL, of Yonkers, Westchester county,State of New York, have invented certain new and useful Improvements inPresses for Printing ou ContinuousSheets ot' Tin-Foil; and we do herebydeclare that t-he'following is a full description of the same.

The object of our invention isto overcome the objection to handlingtin-foil duringthe process of printing, and thereby leaving ink-stainedfinger-marks on it, and at the same time printing it with more rapiditythan it is possible .to-do in single sheets on hand or power-presses;and the nature of our invention consists, rst, in

the combination of a continuons sheet of tin-foil with arevolving-cylinder press, whereby the inking, printing, and carryingforward of the sheet of tin-foil is continuous; secondin combining witha revolving-cylinder press for printing on a continuous sheet oftin-foil an intermittent shear-cutter, for the purpose of severing thetinfoil as it connes from oii` the cylinder into small sheets of'printed matter; third, in combining, with the intermittentshear-cutter, a series of endless bands, for the purpose of Areceivingand carrying otf the subdivided sheets-ot' tin-foil. i

But to describe our invention more particularly, we will refer to theaccompanying drawings, forming n. part of this specification, the sameletters of reference, wherever they occur, referring to like parts.

Figure l is a plan view of the press.

Figure2 is a side elevation of the same. A

Figure 3 is a front end'lview ofthe press, showing the shear-cutter inred outline in theact lof cutting.

Letter A is the frame of the pressfhaving arranged init, on suitablebearings, two cylinders, B and 0oi` equal diameter. On the face of thecylinder Gis secured a series of printing-blocks or plates, D. Theseplates may be made of various sizes to print either large or smallsheets of tin-foil, as may be desired for the ti`dicrent-sized packages.To ink them, a series of inkingand distributing-rollers, E, is rotatedby means of cogwheels F on their ends, gearing intoa large cog-Wheel,Gr, 'on the end of the shaft of the cylinder C. The objectof thiscog-wheel is also. to transmit a uniform rotatory motion through thecog-wheel B2 to the carrying cylinder B, the face of which, beingarranged in close contactI with thevfaee of the cylinder C, so that asthe sheet -oi' tin-foil H (shown by red outlines) from ofi' the reel I(arranged on the under side of the front end of Athe press) passes upbetween theA cylinders B and'G, and back over the cylinder B, it willreceive an impression from the type-plate, and thus he printed withoutthe intervention of any-extraneous pressure or of handling it. Whenprinted, the continuous sheet of foil is carried forward and over theshell J, covering the upper front portion of the cylinder B. The frontedge of the shell forms a straight edge. The object of this shell is,.irst,

f tovcarry the sheet of tin-foil away from the carrying cylinder; and,second, by means of its straight edge, form a bearing, against which acutter may operate to' scvcr the continuous sheet into small Iprintedsheets. 'The cutting device, for severing the shectof tin-foil,ope-rates by means of areciproeating rod, K, attached to a crank, L,rotated by means of two bcvclled-pinion wheels, M, propelled by a wheel,N, -gearing into the cogwheel B2. Toregulate or control the action ofthe cutter in making or subdividing the continuous sheet into large orsmall sheets, the piniocn-whcel N is changed for either a. larger orsmaller wheel, as may be required for the different sizes of printedsheets. '.lhe shear P is attached to a reciprocating rod, K, by an arm,R, and

has a slightly curved or rounded lower edge. The object oi' thiscurvature of edge, inconnection with the.

guide S for holding the reciprocating rod K in a horizontal positionacross the face ofthe press, is to cause the shear to act simultaneouslythroughout its entire cut. 'lo act' otherwise, that is, progressively,as shears ordi*V narily do, would be to cut the foil obliqucly, inconsequence ofthe continuous'motion of the press in delivering thesheet. v

It will bc obvious that this precise arrangement for severing theAsheets of foil, as it comes from the press, v

may bc modified. We have used a- Vrotatory cutter with very goedresults, and for soincpurposes find it te answer very well; but, as arule, weprefer to use the reciprocating cutter, though we do not wish tobe limited to the use ofit to the exclusion of any equivalent devicesfor the purposes set forth.

For the purpose of carrying othe printed sheets of foil W, after beingsevered from-the continuous sheet endless bands T are arranged to runover rollers which are propelled by cog-wheels V gearing into thecogwheel B2, and thus a relative and uniform speed is given to theendless bands to carry off the printed sheets fast enough to prevent thesucceeding printed sheet from falling upon it to soil or dcfaee it.

It will `be obvious that the working of the press willbe effected by theapplication ot' any suitable power, by means of a crank or pulley andbands. As these are common and well known, it is not essential todescribe them. A

Having now described our invention, we will proceed to set forth what wcclaim, and desire to secure by Letters Patent of the United States,preinising, however, that our invention is based upon and limited to thesingle object of printing on a continuous sheet of tin-foil, and not,intended to cover broadly the principle of operation exhibited inrevolving-cylinder printing-presses; it being well knoxi'n that thesubstances of paper `and cloth d'er entirely from tin-foil, whichrequires great delicacy of treatment, not only in printing on it, but

also in handling it, and therefore ns a ncwmatciial, that is, ncontinuons sheet 'of' tin-foil, not at all in conflict with the generalprinciples of printing-presses.

What we claim, therefore, is

1. In combination with a continuous sheet of tin-foil and shell J, theintermittent shear-cutter P, or equiva-l lent therefor, operatingashercnbefore set forth, and for the purposes described.

2. We also claim, in a printing-press for printing on a continuous sheetof tin-foil, the combination of the intermittent shear-cutter with theseries of rollers U and bands T, for the purposes'hereinbefore setforth.
